ROAPE-SOCKET.

SPECIFICATION forming part of Letters Patent No. 499355, dated J' une 20, 1893.

Application filed January 23, 1893. Serial No.459.437. (No model.)

To all whom it may concerm' Be it known that I, DAVID W. BLACK, of Butler, in the connty of Bntler and State of Pennsyl'vania, have inventeda new and useful Improvement in Rope-Sockets, of which the following is a full, clear, and exact description, reference being had to the acconpanying drawings, forming part 'of this specification, in which Figure 1 is a longitndinal sectional View of my improved rope socket; and Figs. 2 and 3 are detached Views of parts of the same.

The object of my in vention is to provide an improved rope socket for use as a deep-well tool, and to avoid the disadvautages incident to former rope sockets which have been difficult to apply and often impossible to free from the rope When it is desired to remove them.

To this end myinvention consists in a rope soeket having wedge slips adapted to cngage with the ropes, means by which the slips are forced positively against the rope so as to hold the same, and means by which the slips may be withdrawn when it is desired to detach the socket from the rope.

In the drawings, 2 represents one of the tubular parts of the socket, having at its lower end the ns'ual threaded portion adapted to be engaged with other tools in the Well, and having at its upper portion a male thread and a projecting end oonstituting the follower 3. On the outer circnmferenee of this` end is an' annular collar 4. -In the lower end of the part 5 of the socket is a recess 6, having a female thread and an inolined seat 7, in which 'ecess the wedge slips 8 are seated, the inclined ends of the slips fitting in the inclined seat. These sli'ps are of segmental conical form and may be of any suitable number, preferably three. On their inner sides they' are preferabl y serrated so that they may hold the rope securely, and their upper ends are conically tapered so as fit in the tapered seat .7. Near the bottom of these slips are the grooves 9, adapted to engage with the collar 4.

The operation is as follows:-The rope 10 is passed through the tubnlar opening in the part 5 of the socket, into the opening in the part 2, the slips 8 are placed around the collar 4 on the follower 3 and around the rope, and are then inserted in the recess 6,and the two parts 5 and 2 are united by screwing them together, the follower 3 carrying the slips S against the i seat 7, which forces the slips againstthe rope so as to hold the same. WVhen it is desired to detach the socket from the rope, the part 2 is unscrewed from the part 5, and as the slips 8 are connected with the follower 3, they may be withdrawn from the reoess 6 by sliding the part 5 np on the rope, and.

being so Withdrawn detach themselves from the rope freeing the same.

The advantages of my invention Will be apparent to those skilled in the art. The rope socket is simple in Construction and is readily applied and removed from the rope.

I claim- A rope socket having a tool connection, an opening for the rope, segmental wedge-slips having an interior groove, a follower having a collar adapted to engage With the groove, and a tape'red seat formed in the body of the socket; substantially as described.

In testimony Whereof I have hereunto set my hand.
